The important starting point is the proper selection and combination of methods that can address a certain topic. Starting from a problem you observe with your subjects or patients or the desire to achieve a better understanding of the
physiological conditions within any activity, you formulate expectations or hypothesis on that particular topic. Usually it is easy to convert assumptions to categories of questions. In the next step you need to decide which biomechanical method
can best detect the processes related to your questions. The selection of a correct biomechanical sensor or class is very important.
